Specification of Letters Patent.

Patented Nov. 13, 1906,

Application flled May 2, 1906. Serial No. 314.754..

l the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description suliicient to enable those skilled in the art to which it pertains to understand, make, and use the same. l

This invention relates particularly to the tracks, abutments, or cams thereon and rollers of a multicolor-printing press-that is, a printing-press wherein more than one color of ink is spread on the type-form from which impressions are made.

The object of this invention is to obtain what may be termed a three-way track for the rollers which are placed on the ends of the inking-rolls to control the color of ink distributed on the inkinfr-rolls and from them to the type-form, and, further, to obtain-threeway tracks of the kind named provided with means to readilyr place thereon abutments arranged to raise the rollers and inking-rolls as they pass over the same in the operation of the press.

A further object of the invention is to obtain mechanism which may be readily attached to the tracks of an ordinary printingpress already in use for one-color ink, and thereby a three-way track be obtained suitable for the use of the press as a iiulticolorpress.

In the drawings referred to, Figure l is a front view of the bed of a printing-press with tracks thereon embodying this invention. Fig. 2 is an elevation on an enlarged scale of one of the recessed metal strips which are secured to the roller-track of a printing-press to obtain a three-way roller-track. Fig. 3 is a top plan view of the recessed striparranged to be secured to an existing roller-track of a printing-press. Fig. 4 is an elevation of a comb made of spring metal,as spring sheetbrass, secured in place to have the teeth thereof located in the recesses of the nt etal strip, which is attached thereover to the eX- isting roller-track of the printing-press. Fig. 5 is a cross-section of the track and comb illustrated in Fig. 4. Fig. 6 is a cross-section on line 6 6 of Fig. 1 of a three-way track embodying this invention. Fig. 7 is an elevation of an abutment removably attachable to the three-way track embodying this invention, and Fig. 8 is a bottom plan view of the abutment illustrated in Fig. 7.

A reference-letter applied to designate a given part is used to indicate such part throughout the several figures of the draw-l ings wherever the same appears.

A A are the tracks for the rollers of inkingrolls heretofore placed along the sides of the bed or platen ofordinary printing-presses to maintain the periphery of the inking-rollsV of the press in proper position relative to the type-form inked thereby.

B B are broken lines, Fig. 1, to indicate inking-rolls, and C C, Fig. 1, are broken lines to indicate rollers on the axles b bof inkingrolls B B.

D D and E E are additional tracks alongside of tracks A A, respectively, and are obtained by securing recessed pieces, Figs. 2 and 3, in place against the tracks A A, as by bolts or screws e e.

The apertures in the three-way track embodying this invention are letteredvF F.

The track D D may extend beyond the bed of the press and alongside of the inking-disks but such extension forms no part of this invention.

G is a strip provided with spring-teeth g g. Strip Gis preferably made of spring metal, as brass, and is secured in place between the sides of tracks A A, respectively, and the pieces attached thereto to form the tracks. D E in such manner that the spring-teeth thereof are within the apertures F F-that is, one of such spring-teeth is contained in each one of such apertures.

H H are abutments provided with body part 7L and head L, respectively. Body part 7L of abutments H H fits into the respective apertures F F, coming in contact with the teeth g g of spring G and heads h of such of the abutments which are inserted in apertures F F of track D come in contact to rest on such track, While those thereof inserted in the apertures of track E rest thereon.

It will be observed that the rollers C C are of suiiicient width to travel on two of the tracks A, D, and E, and when such rollers are placed with the hub thereof adjacent to the inking-roll on the aXle whereof it is placed such roller travels on tracks A and D, and When oppositely placed on an inking-roll it travels on tracks A and E.

Tracks D and E are preferably of the same level as track A g but in no case should they be higher.

It Will be observed that the head h of abutment H is larger than body part h thereof and that thereby a shoulder is obtained Which extends over and rests on the track A. It Will also be observed that Whenever a series ertures G G an elevated track is obtained for the roller running thereover and that the V length of the elevated track is determined by the number of the abutments so placed.

When the roller on the aXle of an inkingroll is traveling on or over an elevated track obtained as described, such inking-roll is vraised from the type-form and does not ink the springs in the apertures, but may severally be easily Withdrawn from one aperture and placed in a diierent one.

By retaining track A the three-Way track embodying my invention is easily constructed in the manner described of the proper height relative to the bed of the press.

Having thus described my invention, what I claim as new7 and desire to secure by Letters Patent, is'- 1. In a printing-press, a three-Way track comprising recessed strips secured to the sides of a central track, in combination with of abutments H H are placed in adjacent apf a spring provided With a plurality of teeth, such teeth respectively corresponding With the recesses in the first-named strips; substantially as described.

2. In a printing-press, a three-Way track comprising recessed strips secured to the sides of a central track, in combination with a spring provided With a plurality of teeth, such teeth respectively corresponding with the recesses in the irst-named strips, and abutments, the body parts whereof fit into the respective recesses and the heads Where of rest upon two of the tracks; substantially as described.
